The Trails Menu (left). Trail Options menu with Distance set as the
update criteria (right).
Update Trail Criteria
The options are automatic, time or distance. When it's in the default
automatic mode, the unit doesn't update the plot trail while you're
traveling in a straight line. Once you deviate from a straight line, the
unit drops a plot point (trail waypoint) onto the trail. This conserves
plot trail points. If a plot trail uses all of the available points allotted to
it, the beginning points are taken away and placed at the end of the trail.
From the Trails Menu, press to
TRAIL OPTIONS|ENT| to UPDATE CRI-
TERIA

The default is 3 seconds. You can also update by distance with a range
from 0.01 to 9.99 mile/nm/km. The default is 0.10 mi.
